Question Scott Roth · Jul 9, 2024

Using the FHIR DEMO, I have pieced together how to make a FHIR Request using OAuth against an External FHIR Repository. When I execute the Patient search (HS.FHIRServer.Interop.Request), I get a HS.FHIRServer.Interop.Response that has a Quick Stream ID, which I then use to convert the Quick Stream to a JSON Dynamic Object. if I do a trace on the Raw JSON Object, I am able to pull out single elements, however I want to pull the raw JSON into a defined Class Structure. 

I tried using fromDao(dao As %DynamicAbstractObject) As <HS.FHIRModel.

Question Victor Castanon · Jul 9, 2024

I'm running into an intermittent issue with some of our Custom Operations/Processes as a result of some large FHIR R4 Binaries. Essentially we get a response from an AthenaHealth FHIR endpoint that appears to be too large to be processed using the IRIS Built In Functions for FHIR:
I've replicated it on the command line here using a file (binary.json) that has the response from the FHIR Endpoint. Not sharing full contents due to PHI concerns.

HSCUSTOM>S file=##class(%Stream.FileCharacter).%New()

HSCUSTOM>Do file.LinkToFile("/data/binary.json")

HSCUSTOM>w file.

Hello Community,

I've configured a FHIR Server in FHIR Configuration "/csp/healthshare/learn1/fhir/r4 " and I enabled a JWT Authentication for this web application. I've invoked this url http://localhost:52773/csp/healthshare/learn1/fhir/r4/login with basic auth get the JWT token. Now I use the access token as a "Bearer" for GET the patient resource. But I got 401Unauthorized error. Anyway I can get the patient resource with basic auth. I tired assign with %ALL role for testing as well. Did I miss any additional configuration in "FHIR Server Configuration"

Hello Community,

I'm a beginner and currently working on a project to convert CCDA files to FHIR using InterSystems IRIS. I have developed a web form to upload CCDA files, and I'm attempting to convert the uploaded CCDA files to FHIR. However, I am encountering an issue where the conversion process results in an empty entry.
Here's the Output it displays on HTML page:

Size of CCDA Stream: 74152
vR4
{"resourceType":"Bundle","type":"transaction","entry":[]}

Here is my code: CCDtoFHIR.csp

Up until recently, I have been toying around with REST/FHIR capabilities but only internally. Now I have a request to make REST API calls outside of our Network. 

I am using an RSA 4096 key, because Microsoft Active Directory Services which generates the signed certificate could not handle the Elliptical Key (ECC) when I put the request in.

  • Others in the Healthcare industry, how have you handled this when there isn't an API manager involved?
  • Do you connect directly through the Interoperability Engine using a TLS key?

IRIS for UNIX (Red Hat Enterprise Linux 8 for x86-64) 2024.1 (Build 267_2U) Tue Apr 30 2024 16:06:39 EDT [HealthConnect:7.2.0-1.r1]

I have a use case where Epic is sending an A60 Allergy transaction is set at the Patient level, but we have a system called VIBE which needs the ADT at an Encounter level instead. Currently we store ADT information in a MS SQL database for years, and we are querying it to get the latest Account Number to insert into the ADT^A60 for VIBE.

This MS SQL Visit Database was built over 20 years ago and is quite cumbersome to keep maintaining.

Question Pietro Di Leo · Jun 13, 2024

Hello everyone,

Recently, I've been working on a Business Process that processes a large JSON FHIR message containing up to 50k requests in an array within the JSON.

Currently, the code imports the JSON as a dynamic object from the original message stream, obtains an iterator from it, and processes each request one at a time in a loop.

The performance meets the requirements, even with much larger requests than the one exposed above.

I'm trying to complete Inferno Service Base URL test for FHIR endpoint and I thought it wanted host.com/fhir/r4/.well-known/smart-configuration but I get header error below. Am I using the wrong Service Base URL List or am I missing something? I'm running 2021.2 HealthShare

ERROR <HSFHIRErr>InvalidAcceptSpec: No valid Accept data found (Accept header or _format parameter)

I am trying to work with the FHIR Object Model where I convert an incoming  HL7v2 to SDA then FHIR. From here I would like to be able to process the FHIR Object by deserializing it to a Bundle object using the following code my problem is I keep on getting an error  which is not explaining much about what is wrong with what I am doing any help will be appreciated  thanks.

Property FHIRAdapter As HS.JSON.AdaptorFHIR;

Method OnRequest(pRequest As HS.Message.FHIR.Request, Output pResponse As HS.Message.FHIR.Response) As %Status
{

             set pmReqFHIRobj=##class(HS.FHIR.Model.Resource.Bundle).

Question Stella Ticker · May 29, 2024

I created a FHIR Client to execute a GET response from an external FHIR server. I set everything up according to this post: https://community.intersystems.com/post/create-fhir-rest-client#comment…

I was able to send a GET request and got a response of type HS.FHIRServer.Interop.Response.

But in the visual trace, I do not see the actual json response payload.  I opened the response object in terminal and saw it has a QuickStreamId, which I used with the HS.SDA3.QuickStream class to open the quickstream object. But how do I get the payload from this quickstream object?

Question Scott Roth · May 28, 2024

I am attempting to make a FHIR call against the Epic Repository through Intersystems. I have setup a Service client per Create FHIR REST Client | InterSystems Developer Community | Business

but I have set it up using OAuth and HTTPS.

I have verified that the OAuth works by executing it manually via a Terminal to verify I get a response. Of course, when I do it is writing to the ISCLOG

I am trying to now test making the FHIR call by initiating the test of HS.FHIRServer.Interop.HTTPOperation, however I keep getting mixed results with first a 404 not found error, and now a 401 unauthorized error.

Question Sebastian Thiele · May 27, 2024

Hi folks,

I am working on a customer project which uses some slightly altered FHIR resources in comparison to default R4 patient resource. I am able to import the structuedefinition as a custom FHIR package and assign it to the ISC FHIR server and the endpoint the IRIS instance provides.

My question is - what is the benefit of using such a custom profil only defining some changes on a resources default definition (e.g. in field optionality)? From my understanding the ISC FHIR server does not validate resources it receives.

Question Santosh K · May 16, 2024

Hi Team,

I am trying to use the inbuilt class: EnsLib.HL7.Service.FileService to pass through an HL7 ADT message as a part of an HL7 to FHIR transformation. We have a client requirement, where we are receiving an NTE segment as a part of the ADT message. I am trying to map the NTE segment to an OBX Segment. I need to implement a counter for OBX segment whenever a NTE segment is found and map the NTE fields to the new OBX segment

How do I implement the counter for OBX?

Thanks

Santosh

Question Scott Roth · May 9, 2024

I am trying to create my first call to our Epic FHIR Repository from Health Connect using Samples-FHIRStarter now that I have OAuth2.0 connection tested/working with our Epic Interconnect URL.

When I take a patient example from our Epic environment and test it through Data.BPL.PatientRecordCollector within the Namespace, I keep getting a 404 - File or directory not found 

as it tells me it cannot find the patient. So, I know the connection is being established, I just can't see what is being sent to Epic to see if I could test it through Postman.

Question Scott Roth · May 7, 2024

Question for folks who have connected to an External FHIR repository outside of IRIS. Within the HS.FHIRServer.Interop.HTTPOperation there is not an option to include TLS or an OAuth authentication when connecting to an external Repository. So then how is that piece done if you need to Authenticate against an OAuth Server before you are able to access the data or call the Web Services/REST calls?
